The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, in one embodiment, a method for determining a lead location for migration is provided, and an implementation subject of the method for determining a lead location for migration according to the embodiment of the present invention is a device capable of implementing the method for determining a lead location for migration according to the embodiment of the present invention, and the device may include, but is not limited to, a mobile terminal and a server, wherein the mobile terminal includes, but is not limited to, a mobile phone, a tablet, a smart watch, and a smart bracelet, and the server includes, but is not limited to, a high-performance computer and a high-performance computer cluster. The method for determining the position of the walking lead specifically comprises the following steps:
step 102, obtaining R-wave amplitudes corresponding to each chest lead, including a V1 lead, a V2 lead, a V3 lead, a V4 lead, a V5 lead, and a V6 lead.
The electrocardiogram is a voltage-time-varying curve, and is recorded on a coordinate line, the ordinate is the voltage, the amplitude is the distance from the upper edge of the baseline to the top point for an upward wave, and the amplitude is the distance from the lower edge of the baseline to the lower end for a downward wave, wherein the baseline is a line corresponding to the T-P section.
As shown in the QRS wave of fig. 2, R wave is upward wave, and S wave is downward wave, so the amplitude of R wave is positive from the peak of R wave to the base line, and the amplitude of S wave is negative from the valley of S wave to the base line.
Fig. 3 shows the orientation of the chest lead on the transverse plane, and it can be seen that the V1 lead, the V2 lead, the V3 lead, the V4 lead, the V5 lead and the V6 lead are located at different positions, and the corresponding angles of the V1 lead, the V2 lead, the V3 lead, the V4 lead, the V5 lead and the V6 lead are: 115 °, 94 °, 58 °, 47 °, 22 °, and 0 °.
And 104, acquiring S-wave amplitude corresponding to each chest lead.
And 106, determining the position of the lead to be migrated according to the amplitude sum of the R wave amplitude and the S wave amplitude corresponding to each chest lead.
In the embodiment of the present invention, the sum of the amplitudes of the R-wave amplitude and the S-wave amplitude is an algebraic sum of the R-wave amplitude and the S-wave amplitude. A lead is said to be negative when the sum of the amplitudes of the R-wave and S-wave amplitudes for the lead is negative, and positive when the sum of the amplitudes of the R-wave and S-wave amplitudes for the lead is positive.
As shown in fig. 4, the traveling guide coupling has the following characteristics: when the QRS ring is in the left posterior position, the V1 lead is negative, the V6 lead is positive, and the shift lead is in the left anterior position; when the QRS loop is in the right posterior position, both the V1 and V6 leads are negative, and the walking lead is in the left posterior position; when the QRS ring is in the right anterior position, the V1 lead is positive, the V6 lead is negative, and the shift lead is in the right posterior position; when the QRS loop is in the left anterior position (e.g., type a pre-excitation), both the V1 lead and the V6 lead are positive, and the walking lead is in the right anterior position.
As shown in fig. 5, the step 106 of determining the position of the walking lead according to the amplitude sum of the R-wave amplitude and the S-wave amplitude corresponding to each chest lead includes: step 106A, calculating to obtain a first amplitude sum according to the R wave amplitude and the S wave amplitude corresponding to the V1 lead; step 106B, calculating to obtain a second amplitude sum according to the R wave amplitude and the S wave amplitude corresponding to the V2 lead; step 106C, calculating to obtain a third amplitude sum according to the R wave amplitude and the S wave amplitude corresponding to the V3 lead; step 106D, calculating to obtain a fourth amplitude sum according to the R wave amplitude and the S wave amplitude corresponding to the V4 lead; step 106E, calculating to obtain a fifth amplitude sum according to the R wave amplitude and the S wave amplitude corresponding to the V5 lead; step 106F, calculating to obtain a sixth amplitude sum according to the R wave amplitude and the S wave amplitude corresponding to the V6 lead; step 106G, determining the position of the lead to traverse according to the first amplitude sum, the second amplitude sum, the third amplitude sum, the fourth amplitude sum, the fifth amplitude sum and the sixth amplitude sum.
For example, the R-wave amplitude of the V1 lead is t1 and the S-wave amplitude is t2, then the sum of the R-wave amplitude and the S-wave amplitude is t1+ t2, i.e., the first sum is t1+ t 2.
Wherein the determining the location of the travel lead from the first, second, third, fourth, fifth, and sixth amplitude sums of step 106G comprises:
106G1, if the first, second, third, fourth, fifth and sixth amplitude sums comprise an amplitude sum having a value of 0, determining the amplitude having the value of 0 and the corresponding target lead.
106G2, determining the position corresponding to the target lead as the position of the antecedent lead.
For example, the first amplitude sum is: 0.2+ (-0.4), the second amplitude sum is: 0.3+ (-0.3), the third amplitude sum is: 0.4+ (-0.3), the fourth amplitude sum is: 0.45+ (-0.25), a fifth amplitude sum of: 0.5+ (-0.2), a sixth amplitude sum of: 0.55+ (-0.15), then amplitude sum of 0 is the third amplitude sum, the third amplitude sum and the corresponding target lead are determined to be the V3 lead, and at the same time, the position 58 ° corresponding to the V3 lead is determined to be the position of the axis of the shift lead, thereby precisely positioning the shift lead position.
Wherein the determining the location of the travel lead from the first, second, third, fourth, fifth, and sixth amplitude sums of step 106G comprises: step 106G3, if the first amplitude sum, the second amplitude sum, the third amplitude sum, the fourth amplitude sum, the fifth amplitude sum and the sixth amplitude sum do not include an amplitude sum with a value of 0, determining the location of the lead to be migrated according to the first amplitude sum and the sixth amplitude sum.
If none of the 6 amplitude sums has a value of 0, then to pinpoint the migrated lead this time it is necessary to determine the location of the migrated lead from the first amplitude sum and the sixth amplitude sum.
Wherein, as shown in fig. 6, the step 106G3 of determining the position of the lead to be migrated according to the first amplitude sum and the sixth amplitude sum includes:
step 106G31, a first angle corresponding to the V1 lead and a second angle corresponding to the V6 lead are obtained.
As shown in FIG. 3, the first angle for the V1 lead is 115 and the second angle for the V6 lead is 0.
Step 106G32, comparing the value of the first amplitude sum with 0 to obtain a first positive and negative result, and comparing the value of the sixth amplitude sum with 0 to obtain a second positive and negative result.
Step 106G33, determining the position of the walking lead according to the first angle, the second angle, the first amplitude sum, the sixth amplitude sum, the first positive and negative result and the second positive and negative result.
In general, from lead V1 to lead V6, the absolute value of the R-wave amplitude gradually increases and the absolute value of the S-wave amplitude gradually decreases, and therefore, the amplitude sum values for different angles are different. In the embodiment of the present invention, the following relationship is defined between the amplitude sum (x) and the angle (y):
y＝kx+λ，
the position of the migrated leads can then be solved according to the linear relationship described above.
Wherein, as shown in FIG. 7, the step 106G33 of determining the location of the migrated lead based on the first angle, the second angle, the first amplitude sum, the sixth amplitude sum, the first positive-negative result, and the second positive-negative result comprises:
step 106G331, if the first positive-negative result is that the first sum of amplitudes is less than 0 and the second positive-negative result is that the sixth sum of amplitudes is greater than 0, determining the position of the migrated lead according to the first angle, the second angle, the first sum of amplitudes and the sixth sum of amplitudes.
In one embodiment, as shown in FIG. 4, the first amplitude sum is less than 0, indicating negative going from the V1 lead, the sixth amplitude sum is greater than 0, indicating positive going from the V6 lead, and the migrated lead is in the left anterior position, without inverting the V1 lead and/or the V6 lead, and determining the location of the migrated lead based directly on the first angle, the second angle, the first amplitude sum, and the sixth amplitude sum. Specifically, the first angle (115 °) and the first amplitude sum (assumed to be represented by a) are substituted into y ═ kx + λ, and the second angle (0 °) and the sixth amplitude sum (assumed to be represented by b) are substituted into y ═ kx + λ, thereby obtaining:
Figure BDA0002225685920000101
since the position of the lead to be migrated is the position where the sum of the amplitudes of the R-wave and S-wave is 0, that is, the angle corresponding to the case where x is 0, λ is obtained, and the position of the lead to be migrated can be obtained.
The compound can be obtained by the formula,
Figure BDA0002225685920000102
converting the above to absolute values is represented by:
Figure BDA0002225685920000103
thus, the lead placement of the walk is
Figure BDA0002225685920000104
In one embodiment, as shown in FIG. 8, the antegrade lead location is determined based on the ratio of angle to the length of the lead wire (the wire of the V1 lead and the V6 lead). At the time when the first amplitude sum is less than 0 and the sixth amplitude sum is greater than 0, as shown in fig. 8(1), the lead wire direction is determined to be the direction from V1 to V6, and then, it is determined that:
the angle V1OA is (115-0 deg.. Xla/(| a | + | b |),
thus, we find the walking lead position λ as: 115 ° -115 °/(| a | + | b |).
Step 106G332, if the first positive-negative result is that the first amplitude sum is greater than 0 and the second positive-negative result is that the sixth amplitude sum is less than 0, obtaining a third angle corresponding to the inverted V1 lead, where the third angle is determined according to the first angle, obtaining a fourth angle corresponding to the inverted V6 lead, where the fourth angle is determined according to the second angle, and determining the position of the walking lead according to the third angle, the fourth angle, the first amplitude sum, and the sixth amplitude sum.
As shown in FIG. 4, the first amplitude sum is greater than 0, indicating positive V1 lead, and the sixth amplitude sum is less than 0, indicating negative V6 lead, where the transposed lead is in the right posterior position, requiring inversion of the V1 and V6 leads. Assuming that the amplitude sum (x) and the angle (y) are represented by (x, y), then for the V1 lead before phase inversion there are: (a, 115 °), the V1 lead was inverted to have: (-a, -65 °), for the V6 lead before phase inversion: (b, 0 °), the V6 lead was inverted to have: (-b, -180 °), so that the third angle is-65 °, the fourth angle is-180 °, substituting (-a, -65 °) and (-b, -180 °) into y ═ kx + λ yields:
